IMPROVEMENT l-N DISINTEGRATING APPARATUS FOR PAPER-PULP.

Specification forming part of Letters Patent No. 155,152, dated September 22, 1874; application filed March 9, 1874.

' To all whom "it may concern:

Be it known that I, FRANQOIS GENIN, of the city of Montreal, in the district of Montreal andProvince of Quebec, Canada, manufacturer of paper, have invented certain new and useful Improvements on Paper Machinery and Chemical Compounds used in Treating Substances to be Converted into Paper-Stock and I do hereby declare that the following is a full, clear, and exact description of the same.

This invention has reference to improvements in machinery for manufacturing 'paperstock from fibrous vegetable substances not having before been manufactured, whereby the work is performed in a better and cheaper manner than by any of the machines at present in use.

To the above remarks I will add that the invention is intended to be used only with that class of vegetable substances which may come under the variety of straws, as, for example, straw proper, rushes, herbe a lien, and all other similar materials.

I will now first describe the mechanism, inserting at the proper intervals the process and chemical ingredients as aforesaid.

In the drawings hereunto annexed, where similar letters of reference indicate like parts, Figure 1 represents a side elevation embodying my invention. Fig. 2 represents a Vertical section of Fig. 1. Fig. 3 represents a plan of washing trough or vat. Fig. 4' represents a sectional plan on line A, Fig. 1. Fig. 5represents a detail plan of revolving grinder. Fig. 6 represents a plan of under side of cover, placed over revolving grinder.

Letter a is the washing-vat in which the cleansing and bleaching process is carried on. This consists of a bottom with sides, constructed in the ordinary manner. If; 1) is a center piece, of equal height with the'sides, forming the trough into an elliptical annular space, 0. Although shown elliptical in the drawings, it may be round, or of any other suitable configuration; but it is advisable to construct it without corners in which the materials to be treated can lodge. Suitably situated in this space 0 is a crushing-wheel, (1, as shown, by

I means of which the first operation of break ing up the material is performed; the wheel being rotated by a pulley or gearing transmitting power in the ordinary manner. This trough may be situated in the upper story of a building or upon a raised platform, and when the material has been sufficiently reduced by the action of the grooved wheel 01 to fiow through a pipe or to the required amount, a plug, 0, in the bottom of the vat may be removed, allowing it to descend by the pipe finto the chamber 9, where it is acted upon by one or more setsof rollers, h, as shown in Figs. 1, 2, and ,4, rotated by power in the ordinary manner, the upper ones revolving toward each other, as indicated by the arrows, as also the lower ones; but it is desirable to have the, periphery of the lower ones traveling at a greater velocity than the upper ones, preventing any tendency to choke or crowd the material in the lower ones. The chamber 9 is formed with hopper-shaped bottom, preventing the material passing down from lodgin g, and obligiu g it to continue its way through the pipe 1', connecting with the cover 70 of the grinder. l is a short cylinder, of which it forms the top cover. This cylinder is. provided with a bottom, m, made in one or attached to it. Ooncentrically with the cylinder 1 is placed a stufling-box and gland, a, forming an opening for the shaft 0 to pass up through. On the upper extremity of this shaft is attached the grinding-diskp, provided with radial grooves q, as shown in Fig. 5. It is also provided with a center upward projection, r, of the form shown, to distribute the material more equally to each section of the grinder. Fig. 6 shows the grooves out in the lower side of the cover k. The parts 19 and k consist of zinc or other suitable metal, with steel plates or knives cast or set in then], while the grooves are formed by leaving spaces between the steel plates or knives. As shown in Fig. 2, the surface of p revolves in very close proximity to, butnot touching, the surface of ksay within an eighth or quarter of an inch. 8 is a pipe connecting the cylinder Z with a spout, t, situated above the washing vat. This is of the configuration shown clearly in Fig. 3, having a double channel, a 'v, and an adjustable diaphragm, m, which may be set at pleasure in the position shown, or in that of the dotted lines at the opposite angle. From this spout an inclined grating or gage, 3 extends to within the vat a, and under the spout t and grating y a trough, z, is formed.

In conclusion with the remarks on the construction of the mechanism, I would add that the shaft 0 is arranged to be rotated, raised, and lowered, to adjust the distance between 70 and p, in the same manner that the shafts of millstones are; or this may be arranged in any other desirable or ordinary way.

I will now proceed to describe the operation of the above machine, together with the process of manufacture and chemical compound used.

The pulp is removed and placed in the space 0 of the trough a. The crushing-wheel d is then set in motion, causing a current in the material, and bringing it in succession under its action. This will be set close enough to break up any lumps or joints in the fiber. After the wheel d has worked the pulp to the proper consistency, the plug 3 may be withdrawn and the material descends by the pipe f to the rollers h. These will reduce it to a liner paste. It will then pass down through the pipe 01 to the grinding-disk 1), previously setin rapid revolution. By the rapid revolution of the disk 10, an amount of centrifugal force will be created sufficient to force the material up the pipe 8 into the spout t, where the diaphragm no will be situated, as shown by the solid line in Fig. 3. The material will then flow along the V side of the spout, and when coming to the grating or perforated inclined diaphragm y, it will descend upon it, during which descent it will be treated to the action of a jet or shower of cold water from spraypipe w, washing and cleansing it, the water passing down through the perforations of the diaphragm into the trough z, from which it will be carried by a waste-pipe. Sufficient of the Water, however, will be allowed. to enter With the pulp into the space 0 a second time to keep the pulp in a proper fluid state. The operation of working over and washing is carried on until the pulp is found to be in a proper state for the class of paper required to be made. The plug 6 is then inserted to prevent the return of the material down the pipe f, the machine being kept in motion till all the material that can be is returned to the space 0.

What I claim as my invention is as follows:

1. The combination of trough c, beater d, pipe f, and rollers h in chamber g with the pipe 4 and with grinding-disk 19, substantially as and for the purpose specified.

2. In combination with the trough 0, provided with the beater, and connected with supplementary rollers beneath, and with a grinding-disk, by suitable pipes, in the manner described, the pipe s, spout t, and inclined grating y, substantially as and for the purposes set forth.

3. The double spout t, having the diaphragm w, and combined and operating in connection with a paper-making machine, in the manner set forth.
